size of the container into which the beverage is v dispensed.

Another object of my invention is to provide a novel and improved-beverage dispensing apparatus of the class described in which the syrup and the charged water may be fed simultaneously from separate sources of supply in a predetermined fixed proportional relationship directly from the said supply sources, thereby eliminating mixing chambers, measuring chambers and similar intermediate compartments.

Still another object of my invention is to provide, in a dispensing apparatus of the class described, novel and improved means for feeding the syrup by pressure and which means shall maintain the feeding flow of said syrup uniform and constant despite variations in the said feeding pressure.

Other objects of my invention will become apparent in the following detailed description there- In the accompanying drawing, in which is shown some of the various possible embodiments of my invention,

Fig. 1 is a side elevational view, partly in section, of a beverage dispensing apparatus constructed and arranged in accordance with my invention;

Fig. 2 is a front elevational view thereof;

Fig. 3 is a view similar to Fig. 1, but illustrating a modified form of my invention; and

Fig. 4 is an enlarged cross-sectional view taken substantially on the line 44 of Fig. 1.

Referring now in detail to the drawing, and more specifically to Figs. 1, 2 and 4 thereof, I have illustrated a beverage dispensing apparatus, constructed and arranged in accordance with my invention and adapted for use in dispensing beverages of the type containing a mixture of. syrup.

and soda water.

The said app ratus may comprise a suitable faucet l having a discharge nozzle H and controlled by a valve ii. The said faucet i0, nozzle known to the art and operated by an oscillative handle l5 fixed to the rotatably mounted shaft [3 for rotation therewith. The said faucet It may be mounted on a supporting wall It by having the tubular portion Illa thereof pass through an opening in the wall I6 and held in position by a nut l1 threadedly received thereon, as shown in Fig. 1. A pipe I8 is threadedly connected to the tubular faucet part Illa by means of the nut IS, the said pipe l8 leading from any suitable, well known source of charged water, well known to the art and which is usually positioned in the cellar or basement of the establishment.

In accordance with my invention, I provide a supply of syrup in any suitable container adapted for the purpose and designed to be fed by pressuremeans in any suitable manner well known to the art, such as for example the tank shown diagrammatically in the drawing. The said syrup is fed from the tank 25 through the pipe 26, through the valve and from thence out through tubing 3!, terminating at a point closely adjacent the discharge end of the nozzle I I, so that the syrup and charged water will flow simultaneously into the tumbler or'any other suitable container. The tubing 8| may pass freely through an opening 32 in the wall 20.

Further, in accordance with my invention, I arrange to supply the syrup at a predetermined pressure in relation to the pressure of the charged water, so that the amount of syrupsupplied will always be in direct proportion to the amount of charged water and as a result, any sized tumbler or container may be filled in a continuous flow without the necessity of first measuring out sepa-- rate quantities of syrup and charged water which must then be led to a chamber and dispensed therefrom by emptying the contents of the mixing chamber into the tumbler. I have found that satisfactory results are obtained by feeding the syrup under a pressure of approximately 25 lbs.

vwhile the charged water is supplied under a pressure of approximately from to lbs.

In accordance with my invention, I have provided the following means for operating my apparatus so that the syrup and charged water. will automatically flow directly from their supply sources by the operation of the single dispensing valve l2, in its customary manner.

The valve handle i5 is provided with a projecting lug portion 40 to which there is pivotally attached the forked end-piece 4| of a rigid rod 42.

. The rod 42 passes freely through an opening 43 II and valve 12 may be of any standard type well 55 in the wall 20 and is provided with another forked end-piece 44. A lever 45-is pivotally connected at one end thereof to the forked end-piece M and at the opposite end is pivotally connected to a forked member I! rigidly attached to a plate 41 which in turn iscarried by the valve 30. The valve 30 is preferably of the type operated by a slidable push button 48, the said push button being so disposed as to be in the path of pivotal movement of the lever 45.

It is thus seen from the above described construction that when it is desired to dispense a soda and syrup mixture, ity is merely necessary to pivotally move the valve handle IS in a clockwise direction, as viewed from Fig. 1 of the drawing, to the dotted line position [5. In the position i5 of the handle i5 the charged 'water will normally flow from the source through the pipe I! and out through the nozzle H. At the same time, it is noted that the rod 4i will have caused the lever 45 to pivotally move in a clockwise direction to the dotted line position 45' to force the push button 48 inwardly and thereby open the valve to permit the flow of syrup from the tank 25 through the pipe 26 and'tubing 3i and into any desired container. Such flow of syrup and charged water will be continuous as long as the valve l2 remains in the last described open position, with the handle in the position I5, or until the supply of syrup or charged water is exhausted. A valve 50 may be provided to control the flow of syrup from the container 25. The lever may be provided with an angularly notched portion 49 to facilitate its contact with the push button 48. If desired, in order to position the end portion 31a of the tubing 3| 'near the discharge end of the nozzle H and to aid in supporting the same, I may provide an apertured projecting lug 5| on the nozzle H, through which the tubing 3 I passes.

It is well known in the art that valves of the type such as I 2 herein disclosed also operate to open position when the handle is swung in a counter-clockwise direction, as, for example, to the position l5" shown in Fig. 1. As can be clearly seen from Fig. l of the drawing my apparatus is so designed that when the valve is opened to the position indicated by the handle l5", charged water alone will be dispensed because of the fact that the lever 45 will be out of contact with-the push button 48 of the valve 30, and therefore the'flow of syrup will stop.

I provide the following construction for the valve 30, designed to maintain the flow of syrup normally maintains the valve head 53 against its seat 85 to stop the flow of syrup through the tube 26. The stem 62 is provided with a shoulder 66 and a spring 68 surrounds the spaced stems BI and 62 and abuts the said shoulder 66 andthe push button 48; I

' It is thus seen from the above described construction that when it is desired to have the syrup flow from the container 25 to the tubing til, it is merely necessary to push the button 40 inwardly against the actions of the springs 64 and 88. While the pressure under which the syrup is fed remains constant, the said syrup will flow through the valve and out. of the tubing end 31a in a constant and uniform flow. However, whenever fiuctuation of the pressure supply, feeding the syrup, occurs, the valve head 63 will be correspondingly moved to alter the space between it and the valve seat 65, so that when there is an increase in pressure, the said space will become smaller and thus limit the amount of syrup flowing through the valve and whenthe pressure under which the syrup is fed, falls, the said space between the valve head 63 and the seat 55 will become larger, thereby permitting a greater quantity of syrup to flow. It is thus seen that valve 30 operates as a governor or regulator to provide a constant rate of flow for the syrup,

In Fig. 3 of the drawing, I have illustrated a modified form of my invention for simultaneously operating the charged water and syrup valves. In this form of my invention, I provide the same faucet H) with its handle l5 and valve I2 leading to a source of supply through the pipe 18. I also provide the same valve 30 for automatically controlling the flow of syrup directly from the source. However, in this form instead of the lever 45 and rod 42 I provide a single lever 10 which is pivotally connected to a forked member H, which, in turn, is rigidly attached to a plate 12 carried by the valve 30. On the valve shaft I 3, I mount a cam 13 for rotation therewith. When the valve handle l5 is moved in a clockwise direction, to the dotted line position IS, the cam 13 is so designed that it we'll pivotally move the lever 10 downwardly to contactively engage and push the button 48 inwardly to open the valve. In this form of my invention, as in the Figs. 1, 2 and 4 form, I provide bendable tubing 14 similar to the tubing 3| for carrying syrup to a point adjacent the discharge nozzle I l. A suitable holding. member I5 may be provided to support the tubing 14. The lever Ill may be provided with a projecting portion to facilitate the operation of the push button 48.

While in the drawing 1 have illustrated my invention as applied to a single faucet N for supplying a beverage, it is-understood that any number of faucets may be mounted on the wall 20 and operated in the same manner.

In accordance with the provisions of the patent statutes, I have herein described the principle and operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof, but I desire to have it understood that the apparatus shown is only illustrative and that the invention can be carried out by other means. Also, while it is designed to use the various features and elements in the combinations and relations described, some of these may be altered and others omitted without interfering with the more general results outlined, and the invention extends to such use.

Having described my invention, what I claim and desire to secure by Letters Patent is:

1. In a beverage dispensing apparatus of the class described, the combination of a source of syrup supply, a source of soda water supply, a dispensing faucet valve for controlling the flow of soda water directly from its source, into a tumbier, and a second valve independent of I said faucet valve for controlling the flow of syrup directly from its source into said tumbler, pressaid syrup therethrough substantially constant despite variations in the said pressure means.

2. In a beverage dispensing apparatus of the type wherein soda water and syrup are fed under different pressures from separate sources of supply into a dispensing tumbler or the like container, that improvement which comprises providing a single control means for causing the simultaneous, continuous flow of soda water and syrup in predetermined proportional speed of flow, in accordance with said different pressures, directly from said sources of supply to said tumbler, said means comprising a first valve for controlling the fiow of said soda water, a second valve independent of said faucet valve for controlling the flow of said syrup, said second valve comprising means for automatically maintaining the flow of said syrup at a constant predetermined pressure despite variations of pressure at the source of syrup supply, said first and second valves being normally in closed position, and means whereby the opening of one valve will cause the simultaneous opening of the other valve.
